Notes:

· The Chain of Custody document and Sample Integrity Sheet are part of the analytical report.

· Any remaining sample(s) for testing will be disposed of one month from the final report date unless other arrangements are made in

advance.

· Sample(s) received, prepared, and analyzed within the method specified criteria unless otherwise noted within this report.

· The results relate only to the samples analyzed in accordance with test(s) requested by the client on the Chain of Custody document. Any

analytical quality control exceptions to method criteria that are to be considered when evaluating these results have been flagged and are

defined in the data qualifiers section.

· All results are expressed on wet weight basis unless otherwise specified.

· All positive results for EPA Methods 504.1, 502.2, and 524.2 require the analysis of a Field Reagent Blank (FRB) to confirm that the results

are not a contamination error from field sampling steps. If Field Reagent Blanks were not submitted with the samples, this method

requirement has not been performed.

· Results contained in this analytical report must be reproduced in its entirety.

· Samples collected by BSK Analytical Laboratories were collected in accordance with the BSK Sampling and Collection Standard Operating

Procedures.

· BSK Analytical Laboratories certifies that the test results contained in this report meet all requirements of the NELAC Standards for

applicable certified drinking water chemistry analyses unless qualified or noted in the Case Narrative.

· Analytical data contained in this report may be used for regulatory purposes to meet the requirements of the Federal or State drinking water,

wastewater, and hazardous waste programs.

· J-value is equivalent to DNQ (Detected, not quantified) which is a trace value. A trace value is an analyte detected between the MDL and the

laboratory reporting limit. This result is of an unknown data quality and is only qualitative (estimated). Baseline noise, calibration curve

extrapolation below the lowest calibrator, method blank detections, and integration artifacts can all produce apparent DNQ values, which

contribute to the un-reliability of these values.

· (1) - Residual chlorine and pH analysis have a 15 minute holding time for both drinking and waste water samples as defined by the EPA and

40 CFR 136. Waste water and ground water (monitoring well) samples must be field filtered to meet the 15 minute holding time for dissolved

metals.

· * - This is not a NELAP accredited analyte.

· Summations of analytes (i.e. Total Trihalomethanes) may appear to add individual amounts incorrectly, due to rounding of analyte values

occurring before or after the total value is calculated, as well as rounding of the total value.

· (2) The digestion used to produce this result deviated from EPA 200.2 by excluding hydrochloric acid in order to produce acceptable

recoveries for affected metals.

· (2C) Result reported from secondary analytical column.

· RL Multiplier is the factor used to adjust the reporting limit (RL) due to variations in sample preparation procedures and dilutions required for

matrix interferences.

MS02 Matrix spike recovery was low; the associated blank spike recovery was acceptable.

MS01 Matrix spike recovery was high; the associated blank spike recovery was acceptable.

DL01 Sample required dilution due to matrix or high concentration of non-target analyte.

BS06 Blank spike recovery for this analyte was biased high; associated samples were ND.

B1.3 Analyte detected in associated method blank. Reanalysis was not attempted because the reported result was >10x that

found in the blank. Sample result may be, in part, attributable to ambient laboratory background.

B1.1 Analyte detected in associated method blank. No material impact on reported result as sample is ND for this parameter.

B1.0 Analyte present in method blank above reporting limit.
